Dipole Antenna Wiring Diagram

If you have plenty of room for a real antenna farm then a separate antenna and feed line for each band is the.

Dipole antenna wiring diagram. The dipole when mounted horizontally radiates most of its power at right angles to the axis of the wire. Tin wire used for electric fence. 100m of speaker wire 2 strands Dipole center you can make your own but this makes life easier PL-259 Male Connectors.

You may have a pair of 70-foot trees perfectly positioned to sup- port a wire beam aimed at your favorite DX area. As the ends appear to be folded back the antenna is called a folded dipole antenna. 08 Quarter Wavelength Vertical Antenna.

You can run the wire straight across the field or better yet use a V shape either inverted or not. In this way it may be possible to angle the antenna to fire in the direction where most contacts are wanted although the dimensions of your garden are more likely to determine what is possible. The antenna consists of two metal rods connected to a receiver R.

The smaller the radius the larger the amplitude of the reactance. Turn all the coils at the same time and connect them properly as you can see in the above diagram. Place a 11 Balun on the Antenna end of the Feedline.

In the text below we will cover the basic rules of antenna construction how to calculate dipole antenna length and explain how to put our wire antenna calculator to work. The larger the wire the wider the bandwidth. See the Ugly Balun Project for instructions on how to build one from coaxBuilding the 10 meter dipole is very easy and simple construction is used with very inexpensive materials you may already have laying around the shack.

The feed line must be within 30 of perpendicular to the dipole and extend a quarter-wavelength to minimize the coax from becoming part of the antenna. The measurements below are for building a simple Dipole Antenna. The reactance of the input impedance is a function of the radius and length of the dipole.
